Abstract: Hydraulic fracturing is a technique for increasing permeability in oil and gas resource development, grouting reinforcement in mine management, and geo-stress measurement. For the purpose of enhancing hydraulic fracturing in horizontal wells, oriented perforating methods have been developed. Fluid is injected into the rock through perforations, which increases fluid pressure within rock and decreases rock temperature. Then, the rock around the perforation is fractured. Therefore, fracture initiation pressure is intimately connected to the physical and mechanical properties, geo-stress, and temperature. Accurate prediction of fracture initiation pressure is crucial in the design and construction of hydraulic fracturing systems. Understanding the properties of the reservoir and state of stress around the wellbore is an effective method to predict fracture initiation.
